My suggestion to you would to read up here on CCF to what exactly real
DDO and
DDR look like. You can search them by using the search box on the top left side of any page here on CCF. Read up on them and you'll be an expert in no time. Remember this too... not every coin is an error coin and
DDO and
DDR error are not very common (and
Machine Doubling is). We're here always to help you in your learning quest!


to the CCF!
